SAFETY VALVE- FOR THE PREVENTION OF THE REFILLING OF BOTTLES.

Application filed October 24, 1924.

This descriptive report refers to a new system of safety-valves which can be applied to all classes of bottles, containers, etc. for liquids, and which offers to merchant and to the fiscal authorities, both with regard to the control of the duties and to the prevention of adulterations, the suflicient guarantee that the bottles cannot be surreptitiously refilled, without leaving visible traces of such refilling.

As will be shown further on, the spout consists of a tubular body, in the interior of which is situated a cut-off chamber, forming the mouth or exit, and this communicates with the interior of said tubular body by means of radial perforations.

This arrangement pervents introduction of any instrument through the mouth of the spout, in any way that might effect the valve. The essential parts of the valve consist of a cap sule displaced by combination with an elastic rubber ring, both capsule and ring being situated in a cavity formed in the said outoff chamber, and so arranged that they sepa rate during the pouring out of the liquid and come together again when it is attempted to reverse the circulation of the liquid, completely preventing this latter being done,

The spout as a whole may be made of any suitable material which will not suffer change by contact with liquids; equally its proportions may be determined in accordance with the container to be used and the amount of outflow required.

- For the clearer understanding of this description the following drawings are attached:

Figure 1, representing the top end of an ordinary bottle, to which a safety spout, constructed according to my invention, has been applied;

Figure 2, showing a central longitudinal section of said spout;

Figures 3 and 4, showing sections along, respectively A.B and CD of Figure 2;

Figure 5, showing the cut-0d chamber in elevation;

Figure 6, showing the capsule which forms the sucker of the valve;

. Figure 7, representing the elastic, ringshaped seat of said capsule.

In these drawings, Figure 1 is the ordinary receptacle, in the neck of which, either by soldering, cementing or in the manufac ture of the receptacle, and in any case in such a way that it can only be extracted by Serial No. 745,558.

unsoldering, or the breaking of the receptacle, the safety spout is fixed. The essential part of the spout is a tubular body, (2)

in the interior of which the cut-off chamber (3) is placed, forming the exit opening (4:) which communicates by means of the radial perforations (5) with the ring-shaped space res)ting between said chamber and the body (2 This ring-shaped space, in its turn, coinmunicates by means of the perforations (6 and 7) with the cavity in which is placed the plug capsule (8), which is displaced by combination with the elastic ring (9), suitably inserted and maintained in the tube (10) that forms the inner mouth, and which, properly soldered, serves as cover to the out off chamber (3) and the body (2).

As shown in Figure 2, by means of the arrows, while the liquid goes out through the lower perforations, the air can enter through the upper ones, and thus produce the running out of the liquid in the same form as it is effected in an ordinary bottle neck.

In whatever position the spout is held in an attempt to introduce liquid into the receptacle, this cannot be achieved, because when the liquid penetrates through the perforations (6,) itcarries the capsule (8) up against the ring (9), thus obstructing the perforation shown by the dotted line Figure 2. The greater the pressure used in at tempting to introduce liquid, the more firmly is this obstruction effected.

The capsule will be of aluminum or some equally suitable material, it being kept as low as possible in order that the circulation of the liquid shall move it in the direction both for opening and for closing.

The ring (9) will preferably be of elastic rubber, for the better circumferential adjus)tment between its edge and the capsule (8 Having thus described and specified the nature of my invention and the method of putting it into practice, I claim as my exclusive invention and property In combination, a receptacle having a neck extension, and a device disposed in said extension for preventing spurious refilling of the receptacle, comprising a tubular body .fixed in the extension, a cut oil member arranged in the body and provided with perforations communicating with the space between the body and member and the exterior of the neck extension, the body being further provided with a skirtportion forming a valve chamber therein and having openings for the passage of fluid between the said space in the body and the interior of said valve chamber, a valve for the latter chamber comprising; a cup shaped shell movable in the chamber end having its closed end directed towards the receptacle, and a resilient extension seat for the receptacle end of the tubular body to receive the closed end of the shell when the latter moves in Contact therewith.
